PURPOSE:To obtain a simple ultraviolet-ray detector, wherein ultraviolet rays are converted into visible light, then it is further converted into visible light having a longer wavelength by a fluorescent material. CONSTITUTION:Ultraviolet rays 1 are converted into visible light by an optical fiber 3 including Ge after passing a filter 2. Said visible light is converted into light having orange color or red color by a fluorescent material 4 at the end of the optical fiber 3. The light converted by the fluorescent material 4 can be observed by the naked eye through an optical fiber 6, which is connected to the optical fiber 3 by a connecting part 7. |
